使用一台 Nicolet-7199B型FT红外光谱仪,备有DGS检测系统和BaF_2(穴口心)的样品池,并将位于3400和2500cm~(-1)区谱图的波数标度分别放大为30和20cm~(-1)/25.4mm,我们观察了四种同位素取代水H_2~(16)O、H_2~(18)O、D_2~(16)O和D_2~(18)O的HO红外振动
A Nicolet-7199B FT infrared spectrometer was used with a DGS detection system and a BaF_2 cell. The wavenumbers at 3400 and 2500 cm -1 were magnified to 30 and 20 cm ~ (-1) /25.4mm, we observed the HO infrared vibration of H_2 ~ (16) O, H_2 ~ (18) O, D_2 ~ (16) O and D_2 ~ (18) O by isotope substitution of water
